振铃光谱技术中腔内光场的涨落计算

THE CALCULATION OF THE FLUCTUATION OF OPTICAL FIELD INTENSITY IN RINGDOWN SPECTRUM TECHNIQUE

采用系综平均理论 ,计算了脉冲激光作为激发光源时 ,激光振铃吸收光谱技术中振铃腔内每个脉冲引起的光场涨落 ,并对计算结果进行了讨论 .

By using ensemble average theory, we have calculated the fluctuation of the optical field intensity which was caused by every laser pulse in ringdown cavity of ringdown absorption spectrum , and the calculated result was also discussed.
